Ukumela impilo randomised trial: preliminary findings of height-adjustable sit-to-stand workstations on health outcomes of South African office workers.
Trial report in BMC research notes, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe prevalence of sedentary behaviour has concurrently risen with multiple cardiometabolic risk markers independent of physical activity levels. Office-based workers accumulate the highest levels of sitting time during occupational times. This study aims to investigate the short-term effects of using height-adjustable sit-to-stand workstations on cardiometabolic risk markers of office-based workers in South Africa.
resultsSixty-two office-based workers were randomized into intervention (n = 44), and the control group (n = 18). Small improvements were observed in BMI, blood pressure, and cholesterol levels in this cohort.
conclusionThis preliminary investigation confirms that short-term height-adjustable sit-stand interventions are effective in reducing workplace sitting time and selected health outcomes. South Africa has been attributed with the highest burden of obesity in Sub-Saharan Africa, as a result, there is a need to implement long-term workplace intervention to reverse these implications.
